There is NOT a rule in the GPL that a GPL based operating system is not allowed to run a closed source software as long as the closed source software does NOT use a GPL licensed part . The main point is that requirement . GPL is so aggressive that , if a closed source software is forking a GPL licensed part for its own operations , owner(s) of the GPL license are saying that the forker software is DEPENDING ON a GPL licensed software , therefore it SHOULD also be an open source software . It is necessary to study GPL license in sufficient detail with all of its implications . Mehmet Erol Sanliturk
